Houseplants create beauty in any indoor room of the home and provide a burst of color in oftentimes colorless landscapes of winter. Red houseplants are especially attractive in a room that craves color and during festive seasons. Whether they rest on a windowsill, fill a tiered plant stand or stand alone on a kitchen counter, houseplants are essential when indoor color calls.
Scarlet star (Guzmania lingulata) is a variety of bromeliad that successfully grows indoors as a houseplant. Scarlet stars do not live in standard potting soil; rather, they grow by clinging to rocks or trees. According to Missouri Botanical Garden, they obtain all their water and nutrients from the air. Scarlet star does well in low light conditions like artificial light and retains its bright red color for an extended period of time, creating an ideal indoor houseplant. They grow 1 to 2 feet tall and wide and produce a globular flowerhead that is comprised of 50 separate white flowers that are nested within their large red bracts. Scarlet star flowers last 2 to 4 months, creating non-stop color within the home. The 18-inch-long, green foliage on scarlet star houseplants forms a funnel-shaped rosette. They grow best in bright, indirect sunlight and warm temperatures, not falling below 60 degrees F.
Anthurium (Anthurium andraeanum) is an herbaceous perennial houseplant to grow indoors in a humid and well-lit room. It grows 1 to 1 1/2 feet tall and has a maximum spread of 1 foot. It features waxy, 6-inch-wide, palette-shaped, bright red spathes with a creamy yellow spadix that shoots up and out of the flower. The long-lasting blooms appear throughout the year, especially in anthurium's optimal growing conditions, and can also be used as a fresh cut flower. The 8-inch-long, dark green, heart-shaped foliage on anthurium creates a clumping effect along the stems and are brilliant year-round. Anthurium grows best in bright to diffused light and well-drained soil with consistent moisture. According to Missouri Botanical Garden, bright indirect light in winter is best.
Amaryllis (Hippeastrum (group)) is a variety of bulb that seasonally blooms indoors and is a popular potted plant during Thanksgiving and Christmas. They grow up to 2 feet tall and 1 foot wide and produce flowers in shades of red, pink and white that sit atop the leafless flowering 12- to 18-inch-long stem or scape. Many amaryllis flowers have spotting and banding, which produce a colorful and showy display. The lance-shaped, large green leaves on amaryllis simultaneously grow with the flowers. Amaryllis requires a bright location within the home, such as an area that receives some morning sun. They do not thrive in direct afternoon sun, so take precautions when placing the plant around the home. Amaryllis grows best in well-drained, humus-rich soil.
